[Feature]: option to disable escape char transformation to display char in scss/css

[mbohovic]

What problem does this feature solve?

I have scss or css file in which, for example, this

.icomoon-calendar:before {
  content: '\e94e';
}

and rsBuild transforms it to this for me

.icomoon-calendar:before {
    content: "";
}

How to prevent it, I want it to stay in flood shape

What does the proposed API look like?

Add a property to the rsBuild configuration for scss processing that disables this transformation
